It is described when receiving shifting commands in embodiment of the disclosure, it is default to judge whether the current torque of motor is greater than
The step of torque, comprising:
When receiving shifting commands, whether the current vehicle speed for detecting the vehicle is less than preset vehicle speed；
If the current vehicle speed of the vehicle is less than preset vehicle speed, judge whether the current torque of the motor is greater than default torsion
Square；
If the current vehicle speed of the vehicle is greater than preset vehicle speed, the shifting commands are not executed.
In the step, in the case where vehicle is in driving status, when receiving shifting commands, working as the vehicle is detected
Whether preceding speed is less than preset vehicle speed.It is to be appreciated that in the case that the speed of operation of vehicle is excessive, if executing gear shift operation,
Vehicle driving safety cannot ensure, also can abrasion to equipment such as vehicular electric machines it is larger, influence the security performance of vehicle.Cause
This, if the current vehicle speed of the vehicle is greater than preset vehicle speed, does not execute the shifting commands when receiving shifting commands,
The current torque of the motor will not be judged, and then ensure the safety in vehicle travel process.

Square decreases below predetermined torque in preset duration, in such cases, the current shift of the vehicle is switched to targeted gear
Position；Alternatively, the torque that the result information is also likely to be motor does not decrease below predetermined torque in preset duration, that is,
It says, when reaching preset duration, the torque of the motor is greater than predetermined torque, no longer expends time waiting motor at this time
Torque decreases below predetermined torque, but the current shift of vehicle is directly switched to target gear.
Specifically, the step 103 may include:
If the torque of the motor decreases below predetermined torque, the current shift of the vehicle is switched into targeted gear
Position；Alternatively,

Alternatively, executing drop torque operation controlling the motor in the another embodiment of the embodiment of the present disclosure
In the process, and in the case where timing duration is less than preset duration, if the torque of the motor does not decrease below predetermined torque,
Then when reaching preset duration, the current shift of the vehicle is switched into target gear.For example, the preset duration is 10s, if
The motor starts to execute drop torque operation, and does not decrease below predetermined torque in 10s, then, will when timing reaches 10s
The current shift of the vehicle switches to target gear.That is, the torque of the motor is big when reaching preset duration
In predetermined torque, the torque for no longer expending time waiting motor at this time decreases below predetermined torque, but directly by vehicle
Current shift switch to target gear.In this way, also drop torque behaviour can be executed to motor when vehicle executes gear shift operation
The time of work is defined, and to fast implement the replacement of vehicle gear in a short time, avoids the execution of the gear shift operation of vehicle
Overlong time also improves the user experience of vehicle so that the gear shift operation of vehicle is rapider, more flexible.
In embodiment of the disclosure, in the case where vehicle is in driving status, when receiving shifting commands, if the electricity
The current torque of machine is greater than predetermined torque, controls the motor and executes drop torque operation in preset duration, and according to the electricity
Machine executes the result information of drop torque operation in preset duration, and the current shift of the vehicle is switched to target gear.This
Sample, can be when vehicle carries out gear shift operation, and control motor carries out drop torque operation in preset duration, is supplied to motor and holds
The time of row drop torque operation, the rapidly transformation of Motor torque is avoided, prevents from generating pause and transition in rhythm or melody when vehicle shift, so that vehicle shift
It is more steady, smooth, improve the comfort of vehicle.
Optionally, in embodiment of the disclosure, the control motor executes drop torque operation in preset duration and can be
Include:
The torque for controlling the motor decreases below the first torque limit in the first preset duration；First torque
Limit value is greater than the predetermined torque；
When the torque of the motor decreases below the first torque limit in the first preset duration, the motor is controlled
Torque decreases below predetermined torque in the second preset duration；First preset duration and second preset duration and
Equal to the preset duration.
For example, the preset duration is 10s, first preset duration can be 6s, then second preset duration is
4s；When the control motor starts to execute drop torque operation, first controls the motor and decrease below the first torque in 6s
Limit value then controls the motor again and decreases below predetermined torque in remaining 4s.Wherein, the first torque limit is greater than institute
Predetermined torque is stated, also allows for first being reduced in the first preset duration larger during controlling motor drop torque operation
The first torque limit, be then reduced to predetermined torque again in the second preset duration.In this way, by the first torque limit and in advance
If the setting of torque and the first preset duration and the second preset duration, so that the drop torque operation of the motor can be realized and pass
